Houlder Ltd on Monday (26 July) said it was awarded the detailed design and engineering for the retrofit of an Air Liquide Boil-Off Gas (BOG) reliquefaction plant by Avenir LNG for its LNG bunker vessel, Avenir Achievement.

The work follows the successful completion of basic design and engineering by Houlder in Q1 of 2022.

Installation of the plant is planned for the end of 2022 ahead of the vessel's first long-term charter with Shell in Q1 of 2023. 

The new TBF700 plant has capacity to reliquefy up to 1Te of BOG per hour, said Houlder in a social media post. 

“The system shall allow Avenir Achievement to maintain its LNG cargo at a low temperature, avoiding ‘LNG ageing’ and maintaining cargo characteristics when bunkering.”

“The system shall prevent losses during idle periods, permitting reliquefication of received cargo vapour after bunkering operations, further reducing wasted cargo and greenhouse gas emissions.”

According to Houlder’s website, the scope of work for the design and engineering for the retrofit of the BOG reliquefaction plant are:

  • Design of new structural modifications and foundations for equipment, including Modification of existing vessel deck house to fit TBF700 and subdivided electrical equipment compartment 
  • Design of new power supplies, switchboard and cabling
  • Design of new LNG pipework interfaces and valve controls 
  • Design of new freshwater & seawater cooling system and pipework
  • Design of HVAC system for new electrical equipment room
  • Complete Class approval package
  • Shipyard Conversion Specification

Houlder have previously completed detailed design and engineering for the installation of five other Air Liquide reliquefaction plants onto LNG carriers.

GCMD concludes its final biofuel blend supply chain trial with Hapag-Lloyd

The Global Centre for Maritime Decarbonisation (GCMD) on Thursday (18 July) said it has successfully completed its final supply chain trial for biofuel blended with very low sulphur fuel oil (VLSFO). 

This marks the end of a series of trials initiated in July 2022 as part of a larger pilot to develop a framework to provide quality, quantity and GHG abatement assurances for drop-in fuels.

In this final trial, bp provided the B30 biofuel blend to the TIHAMA, a 19,870 twenty-foot equivalent unit (TEU) container vessel operated by Hapag-Lloyd.

The biofuel component used is certified to the International Sustainability & Carbon Certification (ISCC) standard – a multistakeholder certification scheme for biobased materials. The biofuel component comprised neat Fatty Acid Methyl Ester (FAME) produced from food waste.

Authentix, a tracer solutions provider, supplied and dosed the FAME with an organic-based tracer at the storage terminal outside the Netherlands. The dosed FAME was then transported to the Port of Rotterdam for blending with VLSFO to achieve a B30 blend, before the blend was bunkered onboard the TIHAMA.

Similar to previous trials, GCMD engaged fuel testing company Veritas Petroleum Services (VPS) to witness the operations at all stages – from biofuel cargo transfer to bunkering. VPS also collected and conducted extensive laboratory tests on samples of the biofuel and biofuel blend collected at pre-determined points along the supply chain to assess quality per Standards EN 14214 and ISO 8217.

With well-to-wake emissions of 13.74 gCO2e/MJ, the neat FAME presented a 85.4% emissions reduction compared to the emissions of the fossil marine fuel. The reduced emissions complies with the MEPC 80, which requires a minimum emissions reduction of 65% in order for biofuels to be classified as sustainable.

GCMD and Hapag-Lloyd determined that consumption of the 4,500 MT B30 blend of FAME and VLSFO resulted in 27.9% emissions reduction compared to sailing on VLSFO.

A newly developed tracer deployed with this supply chain

GCMD collaborated with Authentix to develop and deploy a new organic-based tracer to authenticate the origin and verify the amount of FAME present in the blend. The proprietary tracer blended homogeneously with FAME and was detected at expected concentrations at all sampling points along the supply chain.

This trial marks the first deployment of this tracer in a marine fuel supply chain. Previously, similar tracers were used to authenticate and quantify biofuels in road transport and LPG supply chains.

Development of a comprehensive biofuels assurance framework underway

With the completion of this trial, GCMD has deployed a diverse range of tracer technologies, including synthetic DNA and element-based tracers, in addition to the organic-based tracer used in this trial. The trials have also included the development of a chemical fingerprinting methodology and the evaluation of lock-and-seal and automatic identification systems (AIS) as additional solutions to ensure the integrity of the biofuels supply chain.

Learnings on tracer limitations and benefits will be incorporated into a framework that recommends appropriate use to ensure consistent and robust performance. This effort will complement existing ISCC by providing additional supply chain assurance through physical traceability.

The insights from these trials will be shared in a series of reports covering issues, such as traceability, biofuel degradation, supply chain optimisation and abatement costs. These findings will culminate in a comprehensive assurance framework to provide guidance on biofuels use, slated for release in the fourth quarter of 2024.

Classification society ClassNK on Thursday (18 July) said it signed a Memorandum of Understanding (MoU) with ITOCHU Corporation, Nihon Shipyard Co., Ltd., and Maritime and Port Authority of Singapore (MPA) regarding a joint study for the design and safety specifications of ammonia-fuelled ships which are under development by ITOCHU and partners.

“The discussion for a specification of ammonia-fuelled ships with a governmental body related to their operation is essential for a social implementation of ammonia-fuelled ships,” ClassNK said. 

“As one of parties of the MoU, MPA, a government agency overseeing the world’s busiest bunkering hub, will review and provide their views to the designs of the ammonia-fuelled ships to ensure their safe operations.”

The MoU is based on the premise that 200,000 deadweight ton class bulk carriers will be built by Nihon Shipyard with an ammonia dual-fuelled engine.

“The necessary clarifications of the specification for the ammonia-fueled ship to carry out ammonia bunkering in Singapore will be conducted among parties of this MoU, for the commercialisation of ammonia-fuelled ships,” ClassNK added.

WinGD Completes Successful Tests on New Short-Stroke Methanol-Compatible Engine

Date: July 11, 2024

Key Points:

WinGD has successfully completed testing of its new X52-S2.0 short-stroke engine at the Yuchai Marine Power Co facility. This engine, now type-approved, is available in diesel, LNG, and methanol configurations, with an ammonia option in development. It features a compact design and high fuel efficiency, making it suitable for smaller vessels. The engine's methanol compatibility underscores its role in reducing greenhouse gas emissions and advancing sustainable maritime practices.

Infineum Explores Methanol Fuels for Heavy-Duty and Marine Engines with Innovative Additives

Date: July 11, 2024

Key Points: 

Paul Cooper and Joanna Hughes of Gane Energy spoke to Infineum Insight to discuss the advantages of methanol as fuel for heavy-duty and marine engines and how fuel additives can help to overcome some of the challenges.

One of the issues associated with methanol – in common with many alternative fuels  in marine applications – has been the need to use a pilot fuel to ignite it in the engine. Gane Energy has developed performance additives to methanol fuel, overcoming challenges like lubricity and corrosion. Their approach also eliminates the need for a diesel pilot fuel by converting methanol to dimethyl ether (DME) for ignition.

As the use of methanol grows in various transportation applications, the use of high quality fuel additives will be vital to ensure hardware protection, according to Infineum.
